Question

a number is 3 less than three times another nuber and their sum is 19. then find the number​

Answer 1

Answer:

let the another no. is x

so, the no. will be 3x-3

and

x+(3x-3)=19

x+3x-3=19

4x=19+3

x=22/4

3x-3=3.22/4-3=66/4-3=33/2-3=33-6/2=27/2

Step-by-step explanation:

ans is 27/2

this is the probable ans.

Answer 2

Answer:

The Numbers are 5.5 and 13.5

Step-by-step explanation:

Gívєn -

Number is = 3 less than three times another

Their sum is = 19

Tσ fínd -

The Numbers

Sσlutíσn -

Let the numbers be -

• One as x
• Second as (3x - 3)

$\rule{300}{1.5}$

According to the Question -

Sum of the numbers is 19

➡ x + (3x - 3) = 19

➡ x + 3x - 3 = 19

➡ 4x = 19 + 3

➡ 4x = 22

➡ x = 22/4

➡ x = 5.5

One Number = 5.5

$\rule{300}{1.5}$

Second Number =

➡ (3x - 3)

➡ 3(5.5) - 3

➡ 16.5 - 3

➡ 13.5

Second Number = 13.5

$\therefore$ The Numbers are 5.5 and 13.5

$\rule{300}{1.5}$

Verification :-

Add the Numbers

➡ 5.5 + 13.5 = 19

➡ 19 = 19

➡ LHS = RHS

$\therefore$ The Numbers are 5.5 and 13.5
